Britney Spears Thinks She's Not A "Pretty Cool Chick" Anymore

Britney Spears used to be a "pretty cool chick" but isn't "that way anymore." The 26-year-old singer - who speaks about her comeback following her public breakdown earlier this year in new TV documentary "Britney: For the Record" - thinks she has lost a lot of the personality which shot her to fame in the first place.

She said: "In my situation, I try to make it as normal as possible for me - it could be a lot worse. There are people out there who have it a lot worse than I do. I used to be a cool chick but I feel like the paparazzi has taken that away from me, like, the way I used to live my life. I used to be a cool chick but I'm not anymore."

Britney also spoke about her relationship with "SexyBack" singer Justin Timberlake, who she split from in 2002 after the pair dated for several years.

In the promo for the upcoming documentary, Britney said: "With Justin, he was part of the magnitude of what I had become. So when he was gone I was like, 'What am I supposed to do with myself?' He started to do an album for himself and he started to do things for himself, and I just never saw him anymore. When it ended I felt so alone. I didn't really want to think about the reality of it. I never faced it - I just ran."

Meanwhile, it has been reported Britney will be performing at the American Music Awards in Los Angeles on Sunday.

U.S. TV talk show host Jimmy Kimmel, who is presenting the ceremony, says he has been told there is a surprise in store, but has not been given any further details.

He said: "They have these surprises that 75 people on the crew know about, but they won't tell the host. Apparently, there is some big surprise. I sent the producer an email yesterday and he was like, I can't tell you."
